PEN ETRATING HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent no. 674,343, dated May 14, 1901. Application filed-October 12, 1900. Serial No. 32,829. (No model.)

To all whom it may concern:

Be it known that I, ELBRIDGE W. OAKES, a citizen of the United States, residing at West Bay City, in the county of Bay and State of Michigan,have invented certain new and useful Improvements in Penetrating Hose-Nozzles and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hose-nozzles, and more particularly to hose-nozzlesespecially adapted for penetrating walls of buildings that are afire, driving through partitions for quenching fire in adjacent rooms, or for burrowing into debris, coal-piles, or bunkers of 7 ships and extinguishing fires in them or in similar places situated so as to be inaccessible to an ordinary fire-stream. I

One object of my invention is to provide a hose-nozzle that is simple in construction and capable of being driven either as'a batteringram or by means of sledges or mauls through partitions or into masses of burning fuel without danger of clogging the nozzle-opening or throttling the stream.

A further object is to provide a detachable driving-point that will protect the nozzle end While being driven and will automatically detach itself from the nozzle when the water is turned on,thus insuring free discharge. The point remains embedded in the coal of a bunker that is afire and forms a protection for the nozzle end,while permitting unobstructed flow of water from the nozzle through the mass of coal.

The nozzle is illustrated in the accompanying drawings, throughout the several views,

of which similar characters of reference de'signat corresponding parts.

Figure 1 is a partial vertical section of the nozzle. Fig. 2 is a plan view of the top of the cone-point. Fig. 3 is a side elevation of a perforated cone-point.

As is clearly shown in the drawings, the device consists in a nozzle-pipe 1,having a cap 2 to receive the blows of a sledge in driving, and a side inlet-pipe 3 to be attached to the hose-line. Near the lower end of the pipe 1 driven as far as necessary into the pile.

is secured a collar or equivalent projecting part 4:. A hollow conical point 5 fits over the end of the pipe 1', being held in place by suitable lugs 5 5". The flange 4rests against the top of the lugs 5 and the pipe 1 is normally I prevented from separating from the cone by means of spring-clips 6, which bear upon the upper side of the flange 4. When sufficient force is applied tending to pull the cone from the pipe, the clips press back through open- I ings 6 in the shell of the cone, releasing the flange.

The operation of the penetrating-nozzle is as follows: If a burning coal-bunker is to be quenched, the point of the cone 5 is forced into the mass of coal, and the nozzle is then The water is then turnedon', filling the cone 5 with water under full fire-pressure.

cone, which now serves to prevent the coal .75 from clogging the discharge-orifice.

In the case of a burning building the nozzle can be driven like a battering-ram through an ordinary partition into an adjoining room,

where all parts of the room can be effectually 8o showered by means of the perforated nozzle shown in Fig. 3, or a solid stream can be discharged by the stream forcing off the cone, as above described.

' By this device I am enabled to effectively ;:direct a full fire-stream into piles of fuel and other places where an ordinary fire-hose noz zle cannot reach.

What I claim is 1. In a penetrating hose-nozzle, the combination with a pipe-nozzle, of a driving-head secured in the back end of the pipe-nozzle, a side inlet-pipe for connection with the hoseline, a projecting flange secured to the pipenozzle near its discharge end; and a hollow conical driving-point detachably secured to the end of the pipe-nozzle, and adapted to be released therefrom by the pressure of the water issuing from the nozzle.

2. In a penetrating hose-nozzle, the com- I00 The pressure thus brought upon the nozzle and the under 70 bination of a pipe-nozzlehavinga driving-head at its back end and a side inlet below said head; aprojecting flange secured to the pipenozzle near its discharge end; a hollow conical cap normally embracing the end of the nozzle; projections Within said cap, to receive the impact of the nozzle-collar in driving; and spring-clips back of said collar adapted to normally secure the conical cap to the nozzle, but capable of automatically releasing the cap when the latter is subjected to internal hydraulic pressure.

3. A conical hollow driving-point detachably secured to the discharge end of a hosenozzle, whereby the nozzle may be made to penetrate hard substances; and means whereby the driving-point automatically detaches itself from the nozzle when subjected to interal hydraulic pressure.

L. A hose-nozzle comprising a straight pipe section having a driving-head at its back end and a side inlet between the driving-head and the dischargebpening; together with a hollow conical driving-point secured to the nozzle and embracing its end; comprising means whereby the nozzle may be forcibly driven through resisting substances, for the purposes described.

In testimony whereof I affix my signature in presence of two Witnesses.
